a ricer is someone who has a tastless sense of style when it comes to modifying their car. i may think altezzas are ugly on most cars, but i have seen examples where leaving the stock lights on was even worse. the term ricer is thrown around too much.
example: my friend has a bright pink gs-r sedan (formerly yoolykeme's car). this car has altezzas because of the fact that red, white, and orange tail lights would look absolutely hideous. the altezzas fit the car.
